Pentaquark phenomenology Available to Purchase

Heavy flavor hadron scattering and bound states give experimental information otherwise unobtainable on effective $(qq)6$ and $(q̄q)8$ interactions. All constituent quark model successes in $(uds)$ hadron spectroscopy depend only on $(qq)3,$ and $(q̄q)1$ interactions. Reliable vertex detectors open new pentaquark search directions. Any event in with a proton emitted from a secondary vertex indicates a particle decaying weakly by proton emission and the discovery of a new particle if its mass is higher than that of known charmed baryons. There is no combinatorial background and striking decay signatures like $pφπ−$ are no longer needed.
